problems calling an executable

This is a discussion on problems calling an executable within the C Programming forums, part of the General Programming Boards category; we have 2 executables being called exactly the same way:
concorde : user@host:~/vrp/concorde/TSP$ ./concorde -o tsp_out input_file
linkern : user@host:~/vrp/concorde/LINKERN$ ...

perhaps into a file or something??? if it is a file it would cost too much because these lines of code run hundreds of times solving a genetic. on the other hand you can't make an omelete if you don't break any eggs.
